Should go to a reputable shopping mall to buy a new model of the famous brand, the new factory pressure cooker; if the pressure cooker parts are damaged, you must go to the regular factory to repair or replace; read the instructions carefully before use; pressure cooker during use, on the "cover, hole The five parts of the valve, the ring and the piece should be well maintained. The pressure cooker that has been used for more than 8 years cannot be used even if there is no problem. The biggest difference between the pressure cooker and other pots lies in the word "high pressure". Because of its closed, high-pressure characteristics, it is easy to cook, easy to rotten, and time-saving when processing food, and the loss of nutrition and flavor is relatively small. However, it is well known that it is very dangerous to heat water in a closed container. Since the steam cannot be leaked, the pressure inside the container will be very large, which will easily cause the container to explode. In order to prevent the pressure in the pressure cooker from being too high, the pressure cooker is equipped with a "pressure reducing valve" to allow the pressure inside the pot to leak out of the artificially weakest place in time when the pressure exceeds the specified limit.
The pressure cooker is stamped from high quality aluminum or stainless steel and has a working pressure of 80 to 100 kPa. When selecting a pressure cooker, in addition to whether the surface is smooth or not, there are no alkali stains, oil stains and water stains inside and outside the pot. What is more important is to see if there are pits, defects, scratches, burrs, etc., whether the bottom of the pot and the side of the pot are smooth. It is round and tidy, with or without pores and slag inclusions.
So, is it good whether the aluminum pressure cooker is good or the stainless steel pressure cooker? It depends mainly on the economic strength of the buyer. Because the stainless steel pressure cooker is difficult to make, the price is slightly more expensive than the aluminum pressure cooker. However, in terms of safety performance, as long as the pressure cooker produced according to the national standard GB13623-92, GB15066-94 can ensure the safety of use. However, one must make it clear that no matter which kind of pressure cooker, the period of use should not exceed 8 years, and the consequences of overdue service will definitely not be worth the loss.
According to the annual statistics of the complaints department of the China Consumers Association, the “Quarterly Statistical Table of Major Consumer Complaint Cases†reported by the Consumers Associations of various provinces and cities in 1997 showed that the pressure cooker explosion accounted for more than 20% of the total number of complaints, resulting in 1 death, 7 injuries and a large amount of property. damage. The statistics of major cases in 1998 showed that the pressure cooker explosion accounted for 10% of the total, and three explosions occurred in Sanmen City, Zhejiang Province from September to November. An old man named Zhu Helian used a pressure cooker to cook porridge. The explosion occurred only 8 minutes after the rice was ignited, causing her three fractures and mental disorders. A 25-year-old autoclave explosion victim collapsed because of his eyes and even thought of death.
A comprehensive analysis of the causes of multiple accidents indicates:
The cooking pressure cooker is generally an old standard pressure cooker and a “overdue service†pressure cooker that has been banned from production and sales by the state. Of course, there are cases where the user operates the pressure cooker and the performance and function of the safety component are unclear and cannot be reasonably used. According to the technical supervision department: the old pressure cooker is flawed in design and lacks the necessary safe use of the device. The old standard (ZBY3006-85) has been discontinued since 1993 and the new national standard (GB13623-92) has been activated. However, some pressure cooker manufacturers have not implemented according to the new standards, and some even used new labels on old pots to deceive consumers.
In a sense, the key to the high pressure of the pressure cooker is the pressure cooker apron, and the key to achieving the pressure reduction is the “pressure reducing valve†and the fusible piece.
The pressure cooker gasket is made of rubber as the main raw material, and uses various additives such as a vulcanizing agent, an anti-aging agent, an active agent, a filler, and a coloring agent during processing. In order to reduce production costs, some unscrupulous manufacturers have added some non-food additives, which may cause food pollution and adverse effects on the human body during use. In order to keep the pressure cooker under high pressure, experts suggest that it is best to prepare two rubber rings in the home, one of which is dedicated for cooking oily foods, which can extend the service life of the other rubber ring by 3 to 5 times.
In addition, during the use of the pressure cooker, we must pay attention to the performance of the five safety components of "cover, hole, valve, ring, sheet".
Cover: When the cover is closed, the upper and lower handles should be solid, and then the cover should be opened after cooling down.
Hole: Check whether the vent hole is unobstructed before use, and prevent the blockage and thrust valve from clearing the blockage in time.
Valve: The pressure limiting valve shall not pressurize heavy objects during use, and may not be replaced by other items. The safety valve is vented, indicating that the pressure in the pot has been overpressured. The fire source should be turned off immediately or the micro-fire should be used instead.
Circle: The lid seal should be washed after each use. It should be wet before use. It should be updated immediately when it is aging, leaking or deformed.
Film: This is a safe, low-melting alloy sheet that has been rigorously measured. It must not be replaced by any other metal foil; food debris cannot be attached to the fusible sheet to avoid affecting heat conduction.
